Ngaba yangoku kunye neVoltage iyakuchaphazela ukusebenza kweResistance Spot Welding?

I-Resistance spot welding yinkqubo yokudibanisa esetyenziswa ngokubanzi kumashishini ahlukeneyo, ngakumbi kwimizi-mveliso yeemoto kunye ne-aerospace. Le nkqubo ibandakanya ukusebenzisa umbane kunye noxinzelelo lokudala izibophelelo ezinamandla phakathi kwamaphepha esinyithi okanye amacandelo. Omnye umba obalulekileyo osoloko uphakamisa imibuzo yindima yangoku kunye nombane ekumiseleni umgangatho kunye nokusebenza kakuhle kwee-welds zendawo. Kweli nqaku, siza kuphonononga impembelelo yangoku kunye noseto lwe-voltage kwindawo yokumelana ne-welding.

Ukuqonda Resistance Spot Welding

Ngaphambi kokuba ujonge kwimpembelelo yangoku kunye ne-voltage, kubalulekile ukubamba iziseko zokuxhathisa indawo yokuwelda. Kule nkqubo, iindawo ezimbini zetsimbi ziyaziswa kwaye zixhomekeke kumbane ophezulu. Lo wangoku utyhutyha ngentsimbi kwaye uvelisa ubushushu ngenxa yokuchasana kwayo. Ubushushu bunyibilika inxalenye encinci yentsimbi, idala i-nugget etyhidiweyo epholileyo kwaye iqina ukwenza i-weld.

Indima yangoku

Ukusetwa kwangoku kwi-resistance spot welding idlala indima ebalulekileyo ekumiseleni umgangatho we-weld. Ichaphazela izinga lokushisa, ubungakanani be-nugget, kunye namandla ebhondi ngokubanzi. Nantsi indlela:

1. Iqondo lokufudumeza:Amanqanaba aphezulu angoku akhokelela kwisantya sokufudumeza ngokukhawuleza. Oku kunokuba luncedo kwizinto ezibhityileyo njengoko kunciphisa ukulahla ubushushu kwaye kubangele indawo encinci echatshazelwe bubushushu. Nangona kunjalo, kwimathiriyeli engqindilili, ukugqithisela kwangoku kunokubangela ukutshisa okanye ukutshiza.
2. Ubungakanani beNugget:Okwangoku kuchaphazela ubungakanani be-nugget etyhidiweyo eyenziwe ngexesha le-welding. Amanqanaba aphezulu angoku akholisa ukwenza ama-nuggets amakhulu. Ubungakanani be-nugget bubalulekile kuba buchaphazela ngokuthe ngqo amandla e-joint. Ukungonelanga kwangoku kunokukhokelela kubuthathaka, ama-nuggets angaphantsi, abeka esichengeni ingqibelelo ye-weld.
3. Ukomelela kweBond:Umgangatho we-weld uboshwe ngokusondeleyo kwi-current. Amanqanaba akhoyo alungelelaniswe ngokufanelekileyo aqinisekisa i-weld eyomeleleyo kwaye ehlala ixesha elide. Ukuphambuka kuluhlu lwangoku olucetyiswayo kunokukhokelela kwiibhondi ezibuthathaka kunye nokunciphisa ingqibelelo yesakhiwo.

Indima yeVoltage

I-Voltage, ngokubambisana neyangoku, idlala indima ehambelanayo kwindawo yokumelana ne-welding:

1. Ukuqaliswa kwe-Arc:I-Voltage inoxanduva lokuqalisa i-arc phakathi kwe-electrode kunye ne-workpiece. Kufuneka yanele ukoyisa ukuchasana kwi-electrode-workpiece interface. Amandla ombane aphantsi anokubangela ii-arcs ezingazinzanga kunye nomgangatho ophantsi we-weld.
2. Ulawulo lwe-Weld Pool:I-voltage ikwachaphazela ukumila kunye nokuzinza kwe-weld pool. Inceda ukulawula ukuhamba kwentsimbi etyhidiweyo kwaye iqinisekisa ukuhanjiswa okufanayo, ukuthintela izitenxo kwi-weld bead.

Ukuphucula yangoku kunye neVoltage

Ukufezekisa i-welds yendawo yokumelana nomgangatho ophezulu, kubalulekile ukwandisa zombini useto lwangoku kunye nombane. Oku kubandakanya ukuqwalasela izinto ezifana nobukhulu bezinto eziphathekayo, uhlobo lwesinyithi, kunye noyilo lwe-electrode. Abavelisi bahlala bebonelela ngezikhokelo ze-welding kunye neengcebiso zezinto ezithile kunye nezicelo.

Ukuqukumbela, yangoku kunye ne-voltage zi parameters ezibalulekileyo kwi-resistance spot welding. Ukulungelelanisa ngokufanelekileyo ezi zicwangciso kubalulekile ukuvelisa i-welds ethembekileyo kunye neyomelele. Ukuphambuka kumaxabiso acetyiswayo kunokukhokelela kwiziphene, ukunciphisa amandla ebhondi, kunye nokungaphumeleli kwesakhiwo. Ke ngoko, ukuqonda unxibelelwano phakathi kweziphumo zangoku, zombane, kunye ne-welding kubalulekile ekuqinisekiseni ukusebenza kweenkqubo zokumelana neendawo zokuwelda kumashishini ahlukeneyo.
